There's a difference between people being just plain stubborn, and people with an actual disability that hampers them.
Indeed. I have worked in assistive technology consulting, and it is very difficult to keep up with all of the "upgrades".
It is clear that we value shiny bullshit more than being accessable and inclusive.
And nobody can even make the case that cutting off more and more people from the web even benefits us.
I changed that policy and moved to tracking upstream as closely as I can manage. While it was very hard at first, users have adapted and become better at adapting to new changes quickly. Five years later, I do not see nearly as many "this changed and I don't know how to do it anymore"-type questions as I used to. The initial break was quite hard, but I'm very glad I did it.
